\Header{tsSmooth}{Use Fixed-Interval Smoothing on Time Series}
\methalias{tsSmooth.StructTS}{tsSmooth}
\keyword{ts}{tsSmooth}
\begin{Description}\relax
Performs fixed-interval smoothing on a univariate time series via a
state-space model.  Fixed-interval smoothing gives the best estimate
of the state at each time point based on the whole observed series.\end{Description}
\begin{Usage}
\begin{verbatim}
tsSmooth(object, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{object}] a time-series fit.  Currently only class
\code{"\Link{StructTS}"} is supported
\item[\code{...}] possible arguments for future methods.
\end{ldescription}
\end{Arguments}
\begin{Value}
A time series, with as many dimensions as the state space and results
at each time point of the original series.  (For seasonal models, only
the current seasonal component is returned.)\end{Value}
